12 PCS 70mm Bottom Protective Silicone Sleeve Cup Mat Heat-Resistant Water Bottle Holder Mat Non-Slip Cup Mug Coaster for Insulation Tumbler Protector Bar Coasters - Multicolor

I love these cup mats because they fit my Contigo Cortland water bottle. Don't worry if they seem small, just work the mat onto the bottom of the bottle and it will stay in place. Now when I set my water bottle down on my quartz counters I'm not worried it could chip the counters and it doesn't make any noise.

Brilliant colors and applies easily. Non-slip for bottom of bottle.

Product is good but I specifically ordered the size to fit my 40oz Stanley and it doesn’t fit. It will stretch around it but the edge of the cup and the edge of the silicon don’t line up at the bottom so the cup is wobbly. It fits my 20oz just fine but I didn’t order them for that which is why I didn’t pick that size!

Love these! They fit my 30oz yeti perfectly. They also fit the 26oz yeti stackable cups! Love all the color options and individually wrapped. I was able to gift a few. I recommend!

Product is as advertised, just measure and read carefully. This "70mm" bumper fits many sizes, but not all. From personal experience, it stretched to and worked on a 99mm Yeti - but not even close on a 114mm 40oz hydroflask.

I was stretching one of them out a little to see if it would fit better (and testing it's elasticity). It snapped cleanly apart so it seemed more like a defect. I tried the next one, and it was fine. I have a 30oz and 40oz, and these fit fine.

I ordered these because I have a friend who has them, and they are perfect for a group.The colored rings attach to the bottom of glasses easily, providing a great coaster. And makes your drink identifiable from others. I am planning to order a set of clear acrylic tumblers to use with them.

If you want to prevent scratching any surface these work great.
